Key result
Resting HRV is linked to perceptual well-being in one triathlete but not another.
Why the study?
More understanding of the association between heart rate variability and psychophysiological factors was needed to evaluate personal well-being and prescribe training in athletes.
Does resting heart rate variability correlate with perceptual well-being in triathletes?

Resting heart rate variability may correlate with perceptual well-being in some athletes, but individual variability and methodological limitations highlight the need for further research.
Fluctuations in the intervals between adjacent heartbeats are described as heart rate variability (HRV). In professional sports, HRV is a popular tool to evaluate regeneration and prevent the state of overtraining. HRV measurements could also be used as a simple, non-invasive method to evaluate personal well-being of athletes and prescribe training. However, more understanding in the association between HRV and psychophysiological factors are necessary. Therefore, the aim of this study was to examine the relationship between resting HRV and personal well-being in two triathletes. HRV was recorded at least four times per week for a period of five weeks. Daily personal well-being was assessed via questionnaire. A significant positive correlation between RMSSD and well-being was found for one athlete, while there was no correlation for the other athlete. Further research with bigger sample sizes is needed and should include collection of performance data and other physiological measures.

Bernhard Grässler (2021) conducted a case report in Triathlon training (n=2). Heart rate variability (HRV) monitoring was evaluated on Correlation between RMSSD and perceptual well-being (r = 0.528 (S1); r = -0.191 (S2), p=0.006 (S1); 0.406 (S2)). Resting heart rate variability (RMSSD) showed a significant positive correlation with perceptual well-being in one triathlete (r = 0.528, p = 0.006) but not in a second athlete over five weeks.
